% Code that executes after component creation % Properties that correspond to app components Here is the complete code of App1 (most of the code was generated automatically): classdef App1 < Replace the disp(selected_file) with you own code (loading and plotting the gpx file). The above code displays selected_file string in the Command Window.

Selected_file = fullfile(app.selpath, value) %Get the full path of selected file.ĭisp(selected_file) %Change the code to load selected_file Use fullfile function to concatenate the path with the file name. The value returned value = is the name of the selected file Now selected path is stored in app.selpath.Īdd "ListBoxChangeValue" Callback (right click the list box in design view).Įdit the code of ListBoxValueChanged function: Gpx_files = dir(fullfile(app.selpath, '*.gpx')) %Dir all *.gpx in selected folder. Store the selected path in selpath property when button is pressed: % Button pushed function: ButtonĪpp.selpath = uigetdir() %Open dialog box for selecting folder. Getting the full path of the selected file:Īdd a private property named selpath (use the red P+ in the designer to add new property, and edit the name of the property): properties (Access = private) The statement = Sets the Items property of the ListBox with the created cell array. Gpx_files = dir(fullfile(selpath, '*.gpx')) %Dir all *.gpx in selected folder. Selpath = uigetdir() %Open dialog box for selecting folder. You can do it as follows: % Button button pushed function There are useful resources for automotive competition.You can use dir to list folder's content, convert names list to cell array, and populate the ListBox Items with the cell array.Īssume you have a Button with ButtonButtonPushed callback, and you wish to let the user select a folder, and then populate the list box with all *.gpx files. There are many things you can add or customize the app with MATLAB App Designer, such as increasing the parameters to make it more dynamic by changing the calculation algorithm inside or changing the display format to make it easier for others to see.

The above is a brief overview of the app and how to use it, but this app is static so that even beginners can easily understand it. Click rollCenterCalculator.mlapp in MATLAB.Distance between RC and CG: Difference between the roll center and the height of the center of gravity.Instantaneous Center (IC): Parameters required in the process of calculating the roll center (instant center).

Since the double wishbone suspension is used this time, the mounting points are divided into upper and lower parts, with 2 points on the vehicle body side and 1 point on the wheel side.

Second, information about the mounting position of the suspensionĮach parameter is shown in the picture below.

First, information about a vehicle body.

There are two main types of information that you need to enter in the app.

Unzip the Zip file and open the rollCenterCalculator file in the folder.

If you enter the necessary information in this roll center app, the position of the roll center will be calculated automatically and displayed in 3D. In my case I need to choose a minimum of 2 salts and a maximum of three salts from the list. What you can do with the MATLAB Roll Center App I am a little confused from the videos I have seen it seems the list box in matlab app designer functions as a dropdown list just making it possible to choose one single item. There is a mechanism called a suspension that connects the car body and wheels, and the position of the roll center is determined by how the suspension is attached. Therefore, it is important to know the exact position of the roll center and adjust the position of the roll center so that the car does not lose its balance. Therefore, the car body may turn over when trying to turn a curve. However, the farther the center of gravity and the height of the roll center are, the easier it is for the car to lose balance. So why is the roll center so important? For example, a car has a center of gravity. The roll center is the point of the center (virtual moment) when the object rotates. This app enables teams to modify the code and change the algorithm.īelow I explain the details and would like to hear your feedback on this app and how you might use it. The other day, I created an app for Formula Student teams that automatically calculates the position of the roll center using MATLAB’s App Designer. Nice to meet you, I am Nobu the technical lead for Formula SAE Japan.
